Take A Look Inside Porsche's Stunning Secret Warehouse

A few blocks away from Porsche's swanky museum in Stuttgart, Germany sits a plain and rather unremarkable warehouse whose contents are anything but unremarkable. The facility is where Porsche stores many of its most coveted prototypes and race cars.

Porsche intends to keep the warehouse hidden from public eyes. Fortunately, CAR Magazine's editor-at-large, Chris Chilton, not only got a sneak peak, but also shot video inside the closely guarded facility.

The warehouse stores its priceless contents 'Costco' style, with cars like this early 1990s 968 convertible parked in the aisle alongside racks of 911 and 944 sports cars.

Other Porsches are neatly tucked away under wraps...

The warehouse also houses some of Porsche's most famous race cars, from the brand's illustrious motorsports history. That includes 16 outright victories at the 24 Hours of LeMans and a pair of Formula 1 championships with McLaren.

Check out these early Volkswagen Beetles, designed by Porsche's founder, Ferdinand Porsche.

There are also numerous so-called "mules" — top-secret prototypes that were used to test new technology. Porsche's mules typically looked like existing models, to confuse prying eyes. This one may resemble an early 90s Porsche 964/911 Turbo Targa, but hidden underneath are the mechanicals for the company's then-upcoming Boxster sports car.

These cutaway display models appeared at auto shows around the world.

There are some ugly prototypes in the warehouse. This bizarre creation resembles a 944 from the 1980s.

But gorgeous prototypes abound, including this early four-seat 'long-wheelbase' 911 that never made it into production. In the background, there's a pair of green 'Quaker State'-sponsored March-Porsche Indycars.

The warehouse is home to a collection of ultra-rare 959 supercars. These machines were the most advanced cars in the world when they debuted in the mid-1980s. The 'Rothmans' sponsored race car was prepared for the grueling Paris-to-Dakar Rally.
